DETAILED DESCRIPTION

Various aspects are now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that the various aspects may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing these aspects.

Managing product usage is integral for optimizing usage. Therefore, real-time monitoring of product usage may assist in various use cases, such as toilet paper usage. The product monitoring device discussed herein is either installed into a dispenser or manufactured into a dispenser. Various embodiments discussed herein provided a monitoring system configured to optimize product usage, while also minimizing instances in which product shortages occur. For example, for toilet paper dispensers or paper towel rolls, there may be no time periods in which a given dispenser should be empty. As such, the present disclosure allows for an improved tracking system configured to reduce such instances. Product monitoring devices discussed herein may be capable of measure various types of roll-based technology, such as toilet paper, paper towels, trash bags, and/or the like.

Example Apparatus Configuration

FIG. 1 is a schematic diagram of an example apparatus configured for performing any of the operations described herein. Apparatus 10 is an example embodiment that may be embodied by or associated with any of a variety of computing devices that include or are otherwise associated with a device configured for providing advanced sensory features, which may include a monitoring device 20. In various embodiments, one or more components of the apparatus 10 may be housed independently of other components (e.g., in communication with one another).

The apparatus 10 may include, be associated with, or may otherwise be in communication with a communication interface (not shown), processor 14, a memory device 16, and a monitoring device 20. In some embodiments, the processor 14 (and/or co-processors or any other processing circuitry assisting or otherwise associated with the processor) may be in communication with the memory device 16 via a bus for passing information among components of the apparatus. The memory device 16 may be non-transitory and may include, for example, one or more volatile and/or non-volatile memories. In other words, for example, the memory device 16 may be an electronic storage device (for example, a computer readable storage medium) comprising gates configured to store data (for example, bits) that may be retrievable by a machine (for example, a computing device like the processor). The memory device may be configured to store information, data, content, applications, instructions, or the like for enabling the apparatus to carry out various functions in accordance with an example embodiment of the present invention. For example, the memory device could be configured to buffer input data for processing by the processor. Additionally or alternatively, the memory device could be configured to store instructions for execution by the processor.

The processor 14 may be embodied in a number of different ways. For example, the processor may be embodied as one or more of various hardware processing means such as a coprocessor, a microprocessor, a controller, a digital signal processor (DSP), a processing element with or without an accompanying DSP, or various other processing circuitry including integrated circuits such as, for example, an ASIC (application specific integrated circuit), an FPGA (field programmable gate array), a microcontroller unit (MCU), a hardware accelerator, a special-purpose computer chip, or the like. As such, in some embodiments, the processor may include one or more processing cores configured to perform independently. In some embodiments, the processor 14 may be embodied as one or more processing components (e.g., at least one processor) in a single device or distributed across several devices. A multi-core processor may enable multiprocessing within a single physical package. Additionally or alternatively, the processor may include one or more processors configured in tandem via the bus to enable independent execution of instructions, pipelining and/or multithreading. In some embodiments, each electrode may be in electrical communication with a separate processor and/or memory configured to collectively perform the functions described hererin. Portions of the at least one processor 14 may be powered, while other portions of the at least one processor may remain unpowered during some or all of the detection process.

In an example embodiment, the processor 14 may be configured to execute instructions stored in the memory device 16 or otherwise accessible to the processor. Alternatively or additionally, the processor may be configured to execute hard coded functionality. As such, whether configured by hardware or software methods, or by a combination thereof, the processor may represent an entity (for example, physically embodied in circuitry) capable of performing operations according to an embodiment of the present invention while configured accordingly. Thus, for example, when the processor is embodied as an ASIC, FPGA or the like, the processor may be specifically configured hardware for conducting the operations described herein. Alternatively, as another example, when the processor is embodied as an executor of software instructions, the instructions may specifically configure the processor to perform the algorithms and/or operations described herein when the instructions are executed. However, in some cases, the processor may be a processor of a specific device (for example, the computing device) configured to employ an embodiment of the present invention by further configuration of the processor by instructions for performing the algorithms and/or operations described herein. The processor may include, among other things, a clock, an arithmetic logic unit (ALU) and logic gates configured to support operation of the processor.

The monitoring device 20 may be configured with one or more position sensors 350 (shown in FIG. 3B-3C) configured to determine the distance between the position sensor and the edge of a product (e.g., edge of a toilet paper roll). As discussed in more detail below, the position sensor may be an ultrasonic sensor, a laser sensor, a time of flight sensor, and/or the like. Additionally, the monitoring device 20 may be configured with communication capabilities, such as Wi-Fi, LoRa, Bluetooth, and/or the like, to communication with the processing circuitry 12. In some embodiments, at least a portion of the processing circuitry 12 may be disposed within the monitoring device 20 (e.g., the circuit board of the monitoring device may be configured to carry out one or more operations discussed herein).

FIG. 2A is an example diagram of a monitoring system in accordance with an example embodiment. As shown, the monitoring device 20 may be connected via a network 330 to one or more client devices 101. In various embodiments, the monitoring device 20 may be connected to the network via a wireless communication (e.g., Wi-Fi, Bluetooth, LoRa, and/or the like). In various embodiments, a client device 101 may be defined be one or more types of user interfaces configured to provide information relating to product roll amount in accordance with various embodiments. For example a client device 101 may be one of a mobile phone, tablet, computer, and/or the like. In various embodiments, a client device 101 may be capable of monitoring more than one monitoring device 20 during operations. For example, one client device 101 may have access to each monitoring device 20 for a given area or building. In some embodiments, the client device 101 may receive information from the monitoring device 20 indirectly. For example, the data relating to the product roll amount may be transmitted to the network 330 and at least temporarily stored on a server. In some embodiments, at least a portion of the processing circuitry 12 (e.g., the processor 14 and/or memory 16) may be disposed on the client device 101. For example, the client device 101 may receive raw data from the monitoring device 20 and carry out one or more operations discussed herein.

FIG. 2B shows a specific embodiment of the present disclosure in accordance with the present disclosure. As shown, the monitoring device 20 is installed in a two-toilet paper roll container 200 (e.g., positioned with multiple monitoring sensors as discussed below to monitor both rolls during operation). In various embodiments, the monitoring device 20 may be connected to a gateway 210. In various embodiments, the gateway 210 may connect the monitoring device 20 with the network 330. In various embodiments, one or more client devices 101 (e.g., the mobile phone shown) may be connected to the network 330 and configured to display information to the user. In some embodiments, the information may be provided to the client device 101 within an application.

In some embodiments, the information may be provided to the client device 101 via other communication methods (e.g., via text, email, and/or other typical communication procedures). As shown, the product roll level may be shown in the form of a percentage remaining. In some embodiments, the product roll level may be displayed numerically and/or graphically. In some embodiments, the additional information relating to the product roll may be provided. For example, the estimated time remaining for a given roll, historical usage amount, and/or the like may be provided to the user interface of the client device 101. In some embodiments, the client device 101 may receive one or more notifications relating to the product roll amount during operation. For example, the client device 101 may receive a text message, email, push notification, and/or the like in an instance in which one or more product roll rolls are at a given usage levels (e.g., a notification may be sent when the product roll is less than 30% full and therefore may need to be replaced soon). In some embodiments, a user may be able to select instances in which a notification is received. For example, a company may have a protocol to replace any roll with less than 5% product remaining and therefore the user may select to receive notifications when a given product roll is at or near 5% in order to replace said roll before the roll is completely empty.

In various embodiments, data obtained by a monitoring device 20 may be stored and/or provided to a user. In various embodiments, data tracked over a set amount of time may be used to predict future usage. For example, the amount of time that a product roll is operation between the time installed and the time at which the product roll is emptied may be generally consistent, such that the amount of product roll remaining may be used to estimate the amount of time until the product roll is emptied. Additionally, the data collected over time may be presented to a client device in numerical and/or graphical form, such that a user may be able to order new materials based on usage patterns. For example, different days of the week may have different usage rates, such that a janitor may know that certain bathroom stalls may need to have toilet paper rolls changed more frequently. In various embodiments, the usage data collected may be processed such that various other predictions and/or estimates may be made by the monitoring device 20.

FIGS. 3A-3C are various views of a monitoring device 20 configured to monitor two adjacent product rolls. As shown in FIG. 3A, the monitoring device 20 may define an exterior housing 300. In various embodiments, the exterior housing 300 may be a molded plastic configured with one or more pieces (e.g., multiple molded pieces may fit together to form the housing 300). In various embodiments, the housing 300 may define one or more attachment surfaces 310 configured to attach to another surface, for example, to the interior of a product dispenser (e.g., as shown in FIG. 4B). In various embodiments, the attachment surface 310 may be shaped dependent on a given case. For example, as shown, the attachment surface may define an insert based on the interior of a given product dispenser.

In various embodiments, the exterior housing 300 may define one or more monitoring surfaces 320 configured with an interface for the monitoring sensor to access the product. For example, in an instance the monitoring sensor is a laser sensor, the monitoring surface 320 may define an aperture 335 such that the laser may access a given product roll. In various embodiments, the monitoring surface 320 may be positioned approximately perpendicular to the exterior edge of a given product roll (e.g., perpendicular to the tangent of the exterior edge of product roll). In various embodiments, the angle of the monitoring surface 320 may be based on the position of the monitoring device, the number of sensors in a given monitoring device, and/or the like. For example, the angle of the monitoring surface 320 may be optimized based on the position of the monitoring device within the product dispenser.

FIG. 3B illustrates an exploded view of an example monitoring device 20 in accordance with an example embodiment and FIG. 3C illustrates the example monitoring device 20 with the exterior housing transparent in order to see the positioning of the interior components. As shown, the monitoring device 20 may include the exterior housing 300 (e.g., a top housing 300A and a bottom housing 300B), one or more sensors 350, a circuit board with communication capabilities 360, and a power source 370. As shown in FIG. 3C, the one or more sensors 350 may be positioned along the interior of the monitoring surface 320, such that the sensor 350 can access the product roll via the given monitoring surface aperture 335. In various embodiments, the sensor(s) 350 may be in communication with a circuit board 360 within the exterior housing 300. In various embodiments, at least a portion of the processing circuitry 12 may be disposed on the circuit board 360. In various embodiments, the circuit board 360 includes communication capabilities (e.g., Bluetooth, Wi-Fi, LoRa, and/or the like), such that sensor information may be transmitted (e.g., to the network 330 directly or indirect, such as via a gateway). In various embodiments, the monitoring device 20 may include a power source 370 within the monitoring device. As shown, the power source may be a battery providing power to the monitoring device 20. Other power sources may also be contemplated (e.g., a monitoring device may be hard wired). For example, a photovoltaic solar cell may be used to recharge the power source during operations. In various embodiments, the monitoring device 20 may be self-contained within the exterior housing 300. In various embodiments, the monitoring device 20 may include an attachment mechanism (e.g., adhesive or the like) to attach to a product dispenser or the like. Alternatively, the monitoring device 20 may be integral to a product dispenser (e.g., the exterior housing 300 may be a part of the product dispenser).

FIGS. 4A-4C are example use cases for the monitoring device in accordance with various embodiments. As discussed in more detail below, the monitoring device 20 may be positioned to monitor a product roll 405. In some embodiments, the distance between the sensor and the core of the product roll 420 may be a known, predetermined position distance. In some embodiments, additional position distances may be known that correspond to a given roll amount. For example, the distance between the sensor and the roll in an instance in which the product roll is full may also be known. In some embodiments, the one or more known position distances may be determined during operations (e.g., the position distance between the sensor and a full roll may be reset in an instance in which the roll is replaced). As shown in FIG. 4B, the monitoring device 20 may be positioned between multiple rolls 405A, 405B (e.g., with an individual sensor 350 for each roll). While the monitoring device 20 is positioned at the top of the dispenser in the figures, in various embodiments, the monitoring device 20 may be positioned at different locations within the dispenser (e.g., as long as the sensor 350 remains approximately perpendicular to the surface of the product roll). FIG. 4C shows the distance that is being measured by the sensor. As shown, the position sensor 350 is reading 5 centimeters (e.g., on the user interface), which corresponds to the actual distance shown by the ruler. Additionally, the distance may then be used to determine the remaining amount product for a given roll (e.g., as shown, the product roll may have 34% remaining at an instance in which the position distance is 5 centimeters).

FIG. 5 is a flow chart illustrating an example operation using monitoring devices 20 discussed herein. Referring to Block 500 of FIG. 5, the monitoring system includes means, such as the processing circuitry 12, the processor 14, or the like, for receiving a first position distance between a position sensor and an exterior edge of the roller. In various embodiments, the first position distance may be captured by the monitoring device 20. In the example shown in FIG. 4A, the first position distance 400 is defined as the distance between the monitoring sensor 350 and the exterior edge of the product roll 420 at any given time. In various embodiments, the first position distance may be related to the amount of product remaining on the roll. For example, as the roll of product is used, the first position distance may increase.

Referring now to Block 510 of FIG. 5, the monitoring system includes means, such as the processing circuitry 12, the processor 14, or the like, for comparing the first position distance with a predetermined position distance. In some embodiments, the predetermined position distance defines the distance between the position sensor and the exterior edge of the roller at a specific amount of product left on the roller. In various embodiments, the predetermined position distance may define an instance in which the roll is empty and/or full. In some embodiments, the predetermined position distance may be known based on a given use case (e.g., a standard product roll may be used, such that the predetermined position distance is consistent for every roll). Additionally or alternatively, the predetermined product may be obtained by the position sensor (e.g., the monitoring system may generate the predetermined distance at an instance in which the roll is known to be empty and/or full).

Referring now to Block 520 of FIG. 5, the monitoring system includes means, such as the processing circuitry 12, the processor 14, or the like, for determining the amount of product left on the roller. In some embodiments, the determination of the amount of product left on the roller may be based on the comparison of the first position distance and the predetermined position distance. In some embodiments, in an instance in which a given roll is replaced, the product amount may reset to 100% and then be compared to the predetermined position distance. For example, in an instance in which the predetermined position distance is the distance in an instance the roll is empty, the amount of product may be determined using said distance in comparison to the real-time distance.

Referring now to Block 530 of FIG. 5, the monitoring system includes means, such as the processing circuitry 12, the processor 14, or the like, for causing the transmission of a signal relating to the amount of product left on the roller. In various embodiments, the transmission may include information such as amount of product remaining, estimated time until empty, a usage over time, and/or the like.
